[0028] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0029] As Figures 1-7 shown, a breast pump is provided, which includes a body 1 and a container component 2 provided on the body 1. A connection structure 3 is provided between the body 1 and the container component 2. The container component 2 is detachably connected or locked to the body 1 through the connection structure 3. The connection structure 3 includes a positioning seat 301 provided on the body 1 and a positioning member 302 provided on the container component 2. The positioning member 302 is cooperatively connected with the positioning seat 301 to realize the detachable or fixed connection of the container component 2 to the body 1.

[0030] The container component 2 can be detached through the connection structure 3 conveniently, and the overall structure can be made more stable and reliable; specifically, through the positioning seat 301 provided on the body 1 and the positioning member 302 provided on the container component 2, these two parts cooperate to realize the connection, enabling the user to easily detach or lock the container component 2 to the body; the cooperation of the positioning seat 301 and the positioning member 302 ensures that the container component 2 can be stably fixed on the body 1 during use and can also be detached conveniently when needed.

[0031] Furthermore, as Figures 5-7 shown, a buckle slot 3011 is provided on the positioning seat 301, and a buckle portion 3021 is provided on the positioning member 302. When the container component 2 is fixed to the body 1, the buckle portion 3021 cooperates with the buckle slot 3011; when the positioning seat 301 is pressed, the buckle portion 3021 is disengaged from the buckle slot 3011 to realize the separation of the container component 2 from the body 1.

[0032] Specifically, when the container component 2 is fixed to the body, the buckle portion 3021 is inserted into the buckle slot 3011 to ensure that the container component 2 is stably connected to the body 1, ensuring that the container component 2 is not easily loosened during use, improving the reliability and safety of the product; by pressing the positioning seat 301, the buckle portion 3021 is disengaged from the buckle slot 3011, thereby realizing the rapid detachment of the container component 2, allowing the user to operate with one hand, greatly improving the convenience of use.

[0033] Furthermore, as Figures 5-7 shown, an elastic deformation member 3012 is provided on the positioning seat 301, and the buckle groove 3011 is located on the elastic deformation member 3012. When the positioning seat 301 is pressed, the elastic deformation member 3012 deforms, causing the buckling portion 3021 to disengage from the buckle groove 3011.

[0034] Specifically, the buckle groove 3011 is provided on the elastic deformation member 3012 of the positioning seat 301. When the container component is fixed, the buckling portion 3021 is inserted into the buckle groove 3011, and the elastic force of the elastic deformation member provides a stable fixing force, making the cooperation between the buckling portion 3021 and the buckle groove 3011 more stable and reliable, and avoiding loosening or falling off during use; the design of the elastic deformation member 3012 enables the buckling portion 3021 to be easily disengaged from the buckle groove 3011 when the positioning seat 301 is pressed, with simple operation and good user experience.

[0035] Furthermore, as Figure 6 and Figure 7 shown, a positioning groove 101 for positioning the elastic deformation member 3012 is provided on the body 1, and the elastic deformation member 3012 is inserted into the positioning groove 101, and the elastic deformation member 3012 is arc-shaped.

[0036] Furthermore, a guiding surface 3021a is provided on the buckling portion 3021, and the guiding surface 3021a abuts against the elastic deformation member 3012, thereby pushing the elastic deformation member 3012 to deform, so that the buckling portion 3021 is connected with the buckle groove 3011 in a matching manner.

[0037] Furthermore, as Figure 7 shown, the positioning member 302 extends upward on the container component 2, and an opening 102 for the positioning member 302 to pass through is provided on the body 1.

[0038] Specifically, when the container component 2 is installed, the positioning member 302 passes through the opening 102, and the guiding surface 3021a abuts against the elastic deformation member 3012, pushing the elastic deformation member 3012 to deform, so that the buckling portion 3021 is smoothly inserted into the buckle groove 3011 to complete the mating connection.

[0039] Furthermore, the positioning member 302 is externally disposed at the inlet of the container component 2, and there is a gap between the positioning member 302 and the container component 2 so that the positioning member 302 is away from the inlet of the container component 2. The inlet of the container component 2 and the positioning member 302 are located on the same end of the container component 2, and the inlet of the container component 2 and the positioning member 302 are located on the upper part of the container component 2.

[0040] Specifically, the positioning member 302 is externally disposed at the inlet of the container member 2 and is spaced from the container member 2, so that the positioning member 302 is far from the inlet of the container member 2, ensuring that the positioning member 302 does not interfere with the normal function of the inlet during use; the positioning member 302 and the inlet of the container member 2 are located at the same end of the container member 2 and are both located at the upper part of the container member 2, ensuring the convenience of operation and the independence of functions, and simplifying the structure of the inlet. The inlet is solely used for liquid input, reducing the processing difficulty and production cost of the inlet and improving production efficiency.

[0041] Furthermore, as Figure 1 and Figure 5 show, a button 3013 is provided on the positioning seat 301, and the button 3013 is on the same horizontal plane as the outer peripheral edge of the body 1; alternatively, the button 3013 protrudes from the outer peripheral edge of the body 1.

[0042] Specifically, the button 3013 on the positioning seat 301 is used to press the elastic deformation member 3012 to deform.

[0043] Furthermore, as Figure 4 、 Figure 6 and Figure 7 show, at least two positioning seats 301 are provided, and at least two positioning seats 301 are aligned and arranged on the periphery of the body 1; at least two positioning members 302 are provided, and at least two positioning members 302 are correspondingly arranged on the container member 2 with respect to the positioning seats 301.

[0044] Specifically, the positioning member 302 is provided on the periphery of the container member 2, which can reduce the complexity of the connection between the container member 2 and the body 1 and the complexity of the connection with the three-way member 4, and does not affect the capacity of the container member 2. The capacity of the container member 2 will not be occupied due to the setting of the positioning member 302;

[0045] Through the cooperation of multiple positioning seats 301 and positioning members 302, a more stable and firm connection is provided, avoiding problems such as loosening and falling off that may occur during use.

[0046] Furthermore, as Figure 5 show, the container member 2 includes a container body 201 and a container lid 202. The container lid 202 is installed at the opening at the top of the container body 201. A sealing structure is provided between the container body 201 and the container lid 202. The sealing structure includes a sealing rib 2011 provided on the container body 201 and a groove 2021 provided on the container lid 202. When the container lid 202 covers the container body 201, the sealing rib 2011 cooperates with the groove 2021; the sealing rib 2011 is located at the opening edge of the container body 201.

[0047] Specifically, the design of the sealing rib 2011 and the groove 2021 ensures good sealing performance of the container component 2 during use, achieving a sealing effect, ensuring that the milk liquid in the container body 201 does not leak, and improving the reliability of the product.

[0048] Furthermore, as Figure 3 and Figure 4 shown, a three-way component 4 is provided in the body 1. The three-way component 4 is provided with a negative pressure port 401, an input port 402, and an output port 403. A negative pressure deformation device 5 is provided on the negative pressure port 401, a milk suction bowl 6 is provided on the input port 402, and the output port 403 is communicatively connected to the container component 2; a one-way valve 7 is provided on the output port 403.

[0049] Specifically, the breast pump further includes a negative pressure driving device. The negative pressure deformation device 5 is connected to the negative pressure driving device. The negative pressure deformation device 5 is arranged inside the body 1, and the negative pressure driving device is arranged outside the body 1 or inside the body 1. The negative pressure deformation device 5 generates a stable negative pressure through the negative pressure driving device, ensuring the continuity and stability of the milk suction process, and improving the efficiency and reliability of the breast pump; the one-way valve 7 on the output port 403 ensures that the milk liquid can only flow into the container component 2 unidirectionally, preventing backflow, and ensuring the hygiene and safety of milk storage.

[0050] Furthermore, the negative pressure driving device includes an air pump and a pressure relief valve. The negative pressure deformation device 5 is connected to the pressure relief valve and the air pump through pipelines.

[0051] It should be noted that the air pump includes but is not limited to an electric air pump or a manual air pump. When the air pump is an electric air pump, the negative pressure deformation device 5 is connected to the pressure relief valve and the electric air pump through pipelines; when the air pump is a manual air pump, the negative pressure deformation device 5 is connected to the manual air pump through pipelines.

[0052] Furthermore, the negative pressure deformation device 5 is an airbag.
